FIELD

The present invention relates to drug delivery systems and methods of use thereof for recording administration of a drug dose to a subject. Aspects of the invention include a syringe stopper rod comprising a sensor component that is configured to transmit a report comprising a drug dose completion signal to a data management component, e.g., a mobile computing device.

BACKGROUND

The effectiveness of a medication for the treatment of a given disease or disorder is highly dependent on patient adherence to a defined dosage regimen. A typical dosage regimen may require a patient to receive a medication according to a specific schedule, e.g., two doses per day for a period of several days, weeks or months. The ability of a patient to successfully follow a specified dosage regimen is therefore of paramount importance to the ultimate efficacy of the medication in treating the disease or disorder.

In spite of its importance, patient compliance with a dosage regimen remains a challenge, especially for medications that are self-administered. A patient's non-compliance with a dosage regimen can stem from any number of factors, including, for example, failing to correctly administer the proper dose of the medication, forgetting to administer the medication at a designated time, or failing to record and/or remember the time and date of a previous administration, and therefore failing to correctly determine the time and date at which a subsequent administration should take place. Additionally, a patient may be uncertain as to whether a given lot of a medication has expired, whether the medication has reached a proper temperature for administration following its removal from cold storage, or how much of the medication to administer at a designated time. Furthermore, proper recordation of each medication dose delivered to the patient, as well as additional information relating to the medication itself (e.g., the temperature of the drug at the time of administration) is important to various other parties, including, e.g., health care providers, pharmacies, and drug manufacturers.

As provided herein, aspects of the present invention provide drug delivery systems and methods of use that embody certain advantageous alternatives to existing drug delivery devices and methods, and which address one or more of the needs described above.

In some embodiments, a subject system or device can be configured to administer a drug dose to a patient over a time frame that ranges from about 1 second up to about 30 minutes, such as about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 seconds, or about 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 minutes or more, such as about 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28 or 29 minutes or more. In some embodiments, a subject system or device is configured to remain in a dose-in-progress operational state for a period of time that is equal to the time frame for administering the drug to the patient.

In some embodiments, a sensor component is configured to determine a sleep mode state (e.g., a low power state), wherein the system or device is operating in reduced power mode, and is not ready to administer a drug dose to the patient. In some embodiments, a sensor component is configured to determine a low battery state, wherein the battery charge is below a predetermined level.

Determination of any of the states described herein can be accomplished by analysis of one or more inputs from one or more of the subject sensor components. For example, in some embodiments, a ready state can be determined when a temperature value from a temperature sensor falls within a predetermined range (i.e., indicating that the drug is at a desired temperature range for administration) and a position sensor indicates that the system or device is in a desired position or orientation for administration (e.g., a position of an actuation component is determined to be correct for administration of the drug to the patient).

In some embodiments, a sensor component can communicate a determined operational state, as described above, to another component of the system or device (e.g., to a data management component). In certain embodiments, the data management component can then indicate the operational state to a user (e.g., on a GUI), thereby communicating the operational state to the user. In some embodiments, as described further herein, the subject systems and devices can comprise one or more indicator components that are configured to communicate an operational state of the system or device to a user (e.g., a “ready to inject” operational state).

Sensor components in accordance with embodiments of the invention can be mounted in any suitable location on the subject systems or devices. For example, in some embodiments, a sensor component can be mounted in a housing that is positioned anywhere on the system or device. In one embodiment, a sensor component is mounted in a thumb pad that is attached to an actuation component (e.g., a syringe stopper rod, as described further herein). In some embodiments, a sensor component is configured to be removably coupled to subject drug delivery system or device. For example, in some embodiments, a sensor component is mounted in a thumb pad, and the thumb pad is configured to be removably coupled to a proximal end of a syringe stopper rod. In some embodiments, a sensor component can be mounted in a finger flange component. In certain embodiments, a sensor component is formed into a single unit. In certain embodiments, a sensor component comprises two or more individual units (e.g., two or more different PCBAs) that are electrically connected to one another, each of which is mounted in a suitable location on a subject drug delivery system or device.

Activation Component:

Aspects of the invention include an activation component that is configured to mechanically interact with a sensor component (e.g., a momentary contact switch on a sensor component) when an actuation component has completed a delivery stroke. By relying on a mechanical interaction between an activation component and the sensor component, the subject drug delivery systems and devices provide improved accuracy and reliability regarding their ability to detect successful completion of a delivery stroke of an actuation component. The subject drug delivery systems and devices are configured to transmit a report comprising a drug dose completion signal only when a suitable mechanical interaction has taken place between an activation component and a sensor component. As such, the subject drug delivery systems and devices avoid the shortcomings of other drug delivery systems and devices that rely on electronic perception of a delivery stroke by, e.g., one or more electronic components, such as motion sensors or position sensors, which can malfunction, or fail to accurately perceive or detect the completion of a delivery stroke by an actuation component.

Activation components in accordance with embodiments of the invention can be positioned in any suitable location on the subject systems or devices so that they can mechanically interact with a contact switch upon completion of a delivery stroke by an actuation component. In some embodiments, an activation component is located at a proximal end of an actuation component (e.g., a syringe stopper rod) and is configured to mechanically interact with a contact switch when the actuation component arrives at a specified distal location, thereby completing a delivery stroke. In some embodiments, an activation component is configured to activate a contact switch when the activation component makes physical contact with a portion of a subject system or device. For example, in some embodiments, an actuation component comprises a syringe stopper rod having an activation component at the proximal end, and the activation component is configured to activate a contact switch when the proximal end of the syringe stopper rod makes contact with the proximal end of the syringe barrel.

In some embodiments, an activation component comprises a plurality of individual components that work in concert to activate a contact switch. For example, in one embodiment, an activation component comprises an activation cam that makes contact with a portion of a system or device (e.g., makes contact with a proximal end of a syringe barrel) and a switch key that transfers the physical contact through one or more openings in the sensor housing to activate the contact switch. In some embodiments, an activation cam comprises a plurality of extension tabs that extend from the activation cam to the switch key, and that transfer the physical contact from the activation cam to the switch key.

Turning now to FIG. 2 , a three dimensional exploded view of a syringe stopper rod is depicted. In the depicted embodiment, the activation cam is mounted on a distal face of the sensor housing and comprises a plurality of extension tabs that are configured to pass through a plurality of openings in the sensor housing to contact the switch key. When the extension tabs contact the switch key, the contact switch on the sensor component is activated.

In some embodiments, an activation component is located at a distal end of an actuation component (e.g., a syringe stopper rod) and is configured to mechanically interact with a contact switch when the actuation component arrives at a specified distal location, thereby completing a delivery stroke. For example, in some embodiments, an actuation component comprises a syringe stopper rod having an activation component at the distal end, and the activation component is configured to activate a contact switch when the distal end of the syringe stopper rod makes contact with the distal end of the syringe barrel.

In some embodiments, an activation component comprises a plurality of individual components that work in concert to activate a contact switch. For example, in one embodiment, an activation component comprises an internal rod that extends from the distal end of a syringe stopper rod to a location that is close to a proximal end of the syringe stopper rod, and comprises a plurality of detect notches at its distal end. The detent notches are configured to mechanically interact with one or more detent snaps that are located on the distal end of the syringe stopper rod. When the syringe stopper makes contact with the distal end of the syringe barrel, thereby completing a delivery stroke, the generated force causes the detent snaps to move from one detent notch position to another, in the distal direction. As a result, the internal rod shifts its position with respect to the external rod element, causing the proximal end of the internal rod element to physically interact with the contact switch on the sensor component. Any suitable configuration of detent notches and detent snaps can be utilized in accordance with embodiments of the invention. For example, in some embodiments, an activation component can include one or more detent notches at its proximal end, which are configured to mechanically interact with one or more detent snaps that are located on the proximal end of the syringe stopper rod. In some embodiments, an activation component can include one or more detent notches that are centrally located on the activation component, which are configured to mechanically interact with one or more detent snaps that are centrally located on the syringe stopper rod.

Turning now to FIG. 10 , a three dimensional assembled view of a drug delivery system is depicted. The depicted system comprises a sensor component that comprises two individual units that are electrically connected to one another, each or which is mounted in a finger flange component. The depicted embodiment further comprises an activation component that is mounted on one of the sensor units, and which is configured to be activated when the needle safety device is triggered.

Turning now to FIG. 11 , a three dimensional assembled view of a syringe stopper rod with an exposed cross section is depicted. The depicted embodiment has a sensor component at the proximal end, and is configured to couple to a syringe stopper at the distal end. The depicted embodiment has an internal rod element that has a plurality of detent notches at the distal end, and an external rod element that has a plurality of detent snaps. When the detent snaps shift position in the distal direction from a first detent notch to a second detent notch, the internal rod shifts its position with respect to the external rod, thereby activating the contact switch.

Turning now to FIG. 14 , a three dimensional view of a syringe stopper rod with a trigger switch activation component is depicted. The depicted embodiment has a trigger switch activation component that is located near the proximal end of the syringe stopper rod. During a delivery stroke, the trigger switch activation component is deflected in an inward direction as the proximal portion of the syringe stopper enters the syringe barrel. After deflecting inward at the end of the delivery stroke, the trigger switch activates a contact switch (not shown) disposed inside the syringe stopper rod, thereby activating the sensor component (also not shown).

For example, in some embodiments, an NSD comprises one or more trigger elements that are triggered when the actuation component completes a delivery stroke. In some embodiments, an NSD comprises a trigger element that is triggered when one or more elements of the activation component makes contact with the trigger element, thereby configuring the NSD to be triggered when the activation component contacts the trigger element. In certain embodiments, an activation component comprises a contact switch with a predetermined force value required to activate the contact switch, and an NSD comprises a trigger element with a triggering force requirement that is higher than the predetermined force required to activate the contact switch. As such, a mechanical force that activates the NSD will necessarily activate the contact switch, thereby assuring that the sensor component is activated whenever the NSD is activated. In some embodiments, an NSD is activated simultaneously with activation of the sensor component. In some embodiments, an NSD is activated simultaneously with transmission of a report comprising a drug dose completion signal from the sensor component to the data management component.

In some embodiments, an NSD is configured to be electrically activated by a sensor component. For example, in some embodiments, when a sensor component is activated by an activation component at the completion of a delivery stroke, the sensor component sends an electronic activation signal to the NSD, causing the NSD to activate and sequester the drug delivery cannula.

In some embodiments, when the NSD is activated, the NSD changes position so that the drug delivery cannula is completely surrounded by (or sequestered within) the NSD component. In some embodiments, an NSD is configured to move over a drug delivery cannula. In some embodiments, a drug delivery cannula is configured to move within an NSD. In some embodiments, an NSD is configured to lock into place to sequester the drug delivery cannula inside the NSD when the NSD is activated. This prevents a user from accidentally coming into contact with drug delivery cannula after it has been used.

Turning now to FIG. 7 , a drug delivery system comprising an NSD is depicted. In the depicted embodiment, the NSD is in an activated state, and is extended over the drug delivery cannula to sequester the drug delivery cannula.

In some embodiments, a data management component is configured to indicate to a user that one or more communication components are operational and/or are connected to one or more additional components of the subject drug delivery systems or devices. For example, in some embodiments, a data management component is configured to indicate to a user that the data management component is connected (e.g., via a Bluetooth or WiFi connection) to a subject drug delivery system or device. In some embodiments, one or more indicator components on a subject drug delivery system or device, as described above, can further be used to indicate to a user that the data management component is connected to the system or device. Any suitable combination of indicator components on the data management component and/or the other components of the system or device can be used to indicate a connection status of the data management component to a user (e.g., connected, attempting to connect, not connected, disconnected, etc.).

In some embodiments, a data management component is configured or adapted to receive a report from a subject drug delivery system or device, and to record one or more aspects of the report for purposes of maintaining a patient's medical record/history. For example, in some embodiments, a data management component is configured to receive a report from a system or device that indicates a drug dose was administered to the patient, and the data management component records administration of the drug dose, including the date and time at which the drug dose was delivered. In some embodiments, a report can contain additional information relating to, e.g., the drug that was administered or the patient that received the drug. In some embodiments, a report can contain information relating to one or more operational states of the subject systems or devices. For example, in some embodiments, a report comprises information relating to, e.g., the temperature or temperature history of a system or device. In some embodiments, a report comprises information relating to a geographical location of the drug delivery system at the time of administration. In some embodiments, a report comprises information relating to an anatomical location on a patient's body (e.g., the patient's right arm, or the patient's left leg) where the dose was delivered.

In some embodiments, a data management component is configured or adapted to receive one or more data inputs from a subject system or device, and to validate the one or more data inputs prior to proceeding with administration of the drug to the patient. For example, in some embodiments, a data management component is configured to receive a drug identification characteristic from a subject system or device (e.g., from a drug reservoir that has been coupled to the system or device), and to verify that the drug identification characteristic is valid before proceeding with administration of the drug to the patient. In some embodiments, a data management component is configured to transmit one or more drug identification characteristics over the Internet to a remote database, and to receive an authentication signal in response, prior to administering the drug to the patient.

In some embodiments, a data management component is configured or adapted to determine whether a specific drug delivery system or device, or a component thereof (e.g., a drug reservoir) is the result of an authorized sale from a manufacturer, and/or an authorized prescription of the drug from a prescribing health care provider (e.g., from a prescribing physician), in a specific geographical location (e.g., in a specific country). For example, in some embodiments, a data management component is configured to receive one or more drug identification characteristics from a subject drug delivery system or device (or a component thereof, e.g., a drug reservoir), and to transmit the one or more drug identification characteristics to a remote database. In some embodiments, a data management component is further configured or adapted to transmit a geographical location of the drug delivery system or device to the remote database as well. In some embodiments, a remote database is configured or adapted to compare the one or more drug identification characteristics with the geographical location received from the data management component to determine whether a specific drug delivery system or device, or component thereof (e.g., a drug reservoir), is being used in the geographical location (e.g., the specific country) where it was sold.

In some embodiments, a data management component is configured to validate one or more operational states of the subject systems or devices prior to administration of the drug to the patient. For example, in one embodiment, a data management component is configured to determine whether a drug reservoir is at a temperature that falls within a predetermined acceptable temperature range prior to administering the drug to the patient. In some embodiments, a data management component is configured to verify that a subject system or device is in a “ready” operational state prior to administering the drug to the patient.

Data management components in accordance with embodiments of the invention are configured to determine a date and time at which a drug is administered to a patient (e.g., a time stamp for the drug dose administration). In some embodiments, a data management component is configured to receive a drug dose completion signal from a subject system or device, and is configured to determine the exact time of the drug administration based on additional information transmitted from the system or device. For example, in some situations, a subject system or device may not be operatively connected to a data management component at the specific date and time at which administration of the drug was carried out. In such instances, a subject system or device is configured to determine an elapsed time since completion of the drug administration procedure. When the system or device becomes connected to the data management component, a drug dose delivery signal as well as the elapsed time since the administration is transmitted to the data management component. The data management component then utilizes the transmitted information to back-calculate the specific date and time at which the drug administration procedure was completed, and records this information in the patient's records.

In some embodiments, a subject system or device can comprise a controller, a processor, and a computer readable medium that are configured or adapted to control or operate one or more components of the subject systems or devices. In some embodiments, a system or device includes a controller that is in communication with one or more components of the subject systems of devices, and is configured to control aspects of the systems or devices and/or execute one or more operations or functions of the subject systems or devices. In some embodiments, a system or device includes a processor and a computer-readable medium, which can include memory media and/or storage media. Applications and/or operating systems embodied as computer-readable instructions on the computer-readable memory can be executed by the processor to provide some or all of the functionalities described herein.

In some embodiments, a subject system or device includes a user interface, such as a graphical user interface (GUI), that is configured or adapted to receive an input from a user, and to execute one or more of the methods as described further herein. In some embodiments, a GUI is configured to display data or information to a user.

Preferred Embodiments

In a first preferred embodiment, an actuation component comprises a syringe stopper rod having a distal end and a proximal end, and comprising a hollow, elongated rod element that extends from the distal end to the proximal end. At the distal end, the syringe stopper rod comprises a threaded coupling component that is configured to screw into a syringe stopper. Inside the elongated rod element there is a light pipe and a light pipe diffuser. The light pipe has an elongated shape, and its proximal end is located adjacent to a visual indicator component comprising an LED. The proximal end of the syringe stopper rod comprises a sensor housing, in which is located a sensor component comprising a PCBA, a visual indicator component, a momentary contact switch, and a battery. The sensor housing further comprises a thumb pad located on its proximal face. The thumb pad is removably coupled to the sensor housing to allow access to the sensor component.

The sensor housing of the first preferred embodiment comprises a plurality of openings that allow an activation component to mechanically interact with the momentary contact switch on the sensor component by passing through the sensor housing. The activation component comprises an activation cam that is mounted on the elongated rod element and that is located on an external distal face of the sensor housing. The activation component further comprises a switch key that is mounted on the elongated rod element and that is located on an internal distal face of the sensor housing. The activation cam comprises a plurality of extension tabs that pass through the openings in the sensor housing to contact switch key when the activation cam is activated.

In use, the syringe stopper rod of the first preferred embodiment is connected to a component of a drug reservoir, e.g., a syringe stopper of a pre-filled syringe, and serves as part of an actuation component. The drug delivery system further comprises a housing that surrounds the drug reservoir, a drug delivery cannula, a needle shield, a needle safety device, and a finger flange component. A user then inserts the drug delivery cannula into an appropriate position (e.g., inserts a needle that is operably attached to the syringe under a patient's skin) and then applies a force to the proximal end of the syringe stopper rod, causing the syringe stopper to move in the distal direction and to dispense the drug from the reservoir through the drug delivery cannula and into the patient. When the sensor housing reaches the distal end of the syringe, the delivery stroke is complete. Upon completion of the delivery stroke, the activation cam abuts the distal end of the syringe and the extension tabs of the activation cam exert a force on the switch key, causing it to activate the momentary switch on the sensor component. Activation of the momentary switch triggers the sensor component to transmit a report comprising a drug dose completion signal to the data management component, indicating that the drug dose has been administered to the patient. The data management system records the drug dose administration information in the patient's record. Following administration of the drug dose, the syringe stopper rod can be unscrewed from the syringe and kept for subsequent use, while the used syringe and drug delivery cannula can be disposed of using appropriate biohazard waste disposal procedures. The first preferred embodiment is depicted in FIGS. 2-6 .

In a second preferred embodiment, an actuation component comprises a syringe stopper rod having a distal end and a proximal end, and comprising a hollow, elongated external rod element that extends from a position near the distal end to the proximal end. The actuation component further comprises an elongated internal rod element that extends from the distal end to a position near the proximal end, directly adjacent to a momentary switch on a distal face of the sensor component. At its distal end, the external rod element comprises one or more detent snaps. At a position located just proximal to its distal end, the internal rod element comprises a plurality of detent snap depressions. At the distal end, the internal rod element comprises a threaded coupling component that is configured to screw into a syringe stopper.

The proximal end of the syringe stopper rod comprises a sensor housing, in which is located a sensor component comprising a PCBA, a momentary contact switch, and a battery. The sensor housing further comprises a thumb pad located on its proximal face. The thumb pad is removably coupled to the sensor housing to allow access to the sensor component.

In use, the syringe stopper rod of the second preferred embodiment is connected to a component of a drug reservoir, e.g., a syringe stopper of a pre-filled syringe, and serves as part of an actuation component. The drug delivery system further comprises a housing that surrounds the drug reservoir, a drug delivery cannula, a needle shield, a needle safety device, and a finger flange component. A user then inserts the drug delivery cannula into an appropriate position (e.g., inserts a needle that is operably attached to the syringe under a patient's skin) and then applies a force to the proximal end of the syringe stopper rod, causing the syringe stopper to move in the distal direction and to dispense the drug from the reservoir through the drug delivery cannula and into the patient. When the syringe stopper reaches the distal end of the syringe, the delivery stroke is complete. Upon completion of the delivery stroke, the external rod element exerts a force on the detent snaps, causing them to shift from a more proximal detent snap depression to a more distal detent snap depression, thereby causing the internal rod element to move in the proximal direction with respect to the external rod element. This motion causes the internal rod element to activate the momentary switch on the sensor component.

Activation of the momentary switch triggers the sensor component to transmit a report comprising a drug dose completion signal to the data management component, indicating that the drug dose has been administered to the patient. The data management system records the drug dose administration information in the patient's record. Following administration of the drug dose, the syringe stopper rod can be unscrewed from the syringe and kept for subsequent use, while the used syringe and drug delivery cannula can be disposed of using appropriate biohazard waste disposal procedures. The second preferred embodiment is depicted in FIGS. 11-13 .

In a third preferred embodiment, a drug delivery system comprises an actuation component comprising a syringe stopper and an associated rod element having a distal end and a proximal end. The drug delivery system further comprises a pre-filled syringe, a housing, a needle safety device (NSD) comprising two trigger elements located on each side of the NSD, a needle, a needle shield, and a finger flange component. The finger flange component comprises a sensor housing, in which is located a sensor component that comprises two separate units, each unit comprising a PCBA. The first sensor unit comprises a battery, and the second sensor unit comprises a visual indicator component, a wireless transmitter module, a memory component, and an activation component. The first and second sensor units are electrically coupled to one another. The finger flange component is removably coupled to the housing of the drug delivery system. The activation component is located on a proximal face of the finger flange component, and is configured to be activated when the proximal end of the syringe stopper rod mechanically contacts the NSD trigger elements and activates the NSD.

In use, a user removes the needle shield and inserts the needle into an appropriate position (e.g., inserts the needle under a patient's skin), and then applies a force to the proximal end of the syringe stopper rod, causing the syringe stopper to move in the distal direction and to dispense the drug from the drug reservoir through the needle and into the patient. When the syringe stopper reaches the distal end of the syringe, the delivery stroke is complete. Upon completion of the delivery stroke, the proximal end of the syringe stopper rod mechanically contacts the trigger elements of the NSD, thereby triggering the NSD and causing it to sequester the needle. Triggering the NSD also activates the activation component, which triggers the sensor component to transmit a report comprising a drug dose completion signal to the data management component, indicating that the drug dose has been administered to the patient. The data management system records the drug dose administration information in the patient's record (e.g., in a computer application that is installed on the data management component). Following administration of the drug dose, the finger flange component can be removed from the system and kept for subsequent use, while the used syringe and drug delivery cannula can be disposed of using appropriate biohazard waste disposal procedures. The third preferred embodiment is depicted in FIGS. 7, 8 and 10 .

In some embodiments, the subject methods comprise authenticating a drug in a subject system or device prior to administering the drug to the patient.

In one embodiment, a subject method comprises inserting a drug delivery cannula of a subject drug delivery system into a patient and completing a delivery stroke of the actuation component, thereby causing the activation component to activate the sensor component, causing a wireless transmitter module in the sensor component to transmit a report comprising a drug dose completion signal to the data management system. Upon receipt of the report, the data management system records administration of the drug dose to the patient. By automating this step, the user is ensured of more accurate record keeping regarding administration of the drug. In addition, other parties, such as a treating physician or health care network, can have greater access to more accurate information regarding the patient's medical record, e.g., the history of administration of the drug.

In some embodiments, the subject methods comprise a validation or verification step in which one or more data values are received from the subject drug delivery systems or devices, and are validated or verified to determine whether the drug is suitable for administration to the a patient. In some embodiments, the subject methods comprise verification of one or more drug identification characteristics, e.g., a drug identification number, in order to confirm the authenticity of the drug. In some embodiments, the subject methods comprise analyzing a plurality of data collected from the sensor component of a subject drug delivery system or device to evaluate one or more environmental parameters. For example, in one embodiment, the subject methods comprise analyzing the temperature history of a drug reservoir to verify that the drug reservoir has been maintained under required temperature conditions prior to administration of the drug to the patient. By including a sensor component on the subject systems and devices, many of the steps associated with verifying the authenticity and condition of a given drug can be done automatically using a data management component, providing greater ease of use to the end user, and providing more accurate safety and administration information.

In some embodiments, the subject methods comprise utilizing a computer application (e.g., a mobile application) on a subject data management component that is configured or adapted to facilitate improved patient adherence to a drug dosage regimen by recording the date and time of each administration of a drug to the patient. In some embodiments, the methods involve recording the date and time of each administration of a drug dose to the patient so that the patient can be accurately reminded when the next administration of the drug dose should take place in accordance with a prescribed drug dose regimen. In some embodiments, the subject methods involve sending a reminder to a patient that a drug dose is due to be administered at a designated time. For example, in some embodiments, the subject methods involve sending one or more regularly-scheduled reminders to the patient to administer a dose of a drug. In some embodiments, the subject methods comprise sending a reminder to the patient at a predetermined time, e.g., every day at a specific time. In some embodiments, the subject methods involve determining when a subsequent dose of a drug is due to be administered to a patient based on the patient's prior administrations of the drug, and sending a reminder to the patient at a predetermined time, (e.g., about 1 hour, about 30 minutes, or about 10 minutes) before the drug dose is due to be administered. In some embodiments, the subject methods involve monitoring a patient's adherence to a drug dosage regimen, and sending a notification to one or more third parties if the patient is not adequately adhering to the dosage regimen. For example, in some embodiments, the subject methods comprise sending a notification to one or more members of a patient's family if the patient is not adhering to the dosage regimen. In some embodiments, the subject methods comprise sending a notification to one or more health care providers (e.g., to a prescribing physician) if the patient is not adhering to a dosage regimen.

Aspects of the invention include Internet-based computing techniques (also known as “cloud computing” techniques) that involve sending and/or receiving information to or from one or more shared computer processing resources and/or data repositories over the Internet at the time such resources are needed or used by a user. Such techniques allow a user to utilize sophisticated computing equipment without being required to personally purchase and maintain the equipment. In addition, Internet-based computing techniques facilitate access to user information by patient-authorized third parties, such as, e.g., health care providers, or drug manufacturers.

In some embodiments, the subject methods comprise sending one or more drug identification characteristics to a remote database, and receiving, in response, one or more additional drug identification characteristics that can be recorded by the data management system. For example, in one embodiment, the subject methods comprise receiving a first drug identification characteristic (e.g., a drug lot number) from a subject system or device, and transmitting the first drug identification characteristic to a remote database using the data management component. The remote database uses the first drug identification characteristic to retrieve one or more additional drug identification characteristics, which are then transmitted back to the data management component.

Aspects of the invention relate to methods for monitoring the progress of a clinical trial. In some embodiments, the subject drug delivery systems and devices can be used to electronically track one or more individual patients in a clinical trial, and to record one or more items of information associated with each administration of a drug. For example, in some embodiments, the subject drug delivery systems and devices can be used to monitor the progress of a clinical trial while providing adequate protection of the rights of any human subjects involved the clinical trial by rendering the data anonymous to any personnel who are administering the trial. The subject systems and devices can be used to transmit and/or store information relating to successful administration of a drug dose to a patient, and the information can be reviewed by personnel administering the clinical trial to monitor the progress of the clinical trial. In some embodiments, the subject systems and devices can be used to record one or more drug identification characteristics, such as, e.g., a drug lot number, for each patient in a clinical trial. At any point during the progress of the trial, and/or at the completion of the trial, the drug identification information can be used to analyze the results of the trial, e.g., to determine patient response as a function of one or more drug identification characteristics.

In some embodiments, the subject methods result in improved patient adherence to a drug dosage regimen. For example, in some embodiments, implementation of the subject methods, as described above, results in an increase in patient adherence to a drug dosage regimen by an amount that ranges from about 1% up to about 75% or more, such as about 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, or about 70% or more.

In some embodiments, the subject methods comprise separating one or more components of the subject systems and devices following administration of the drug to the patient, and separately disposing of the individual components. For example, in one embodiment, a portion of a subject system or device that comprises electronic components (e.g., a circuit board component, a power component, etc.) can be separated from the remainder of the device and disposed of according to electronic waste handling procedures. Separation of the electronic components from the remainder of the device reduces the amount of electronic waste, as the non-electronic components (e.g., the housing, the drug reservoir, etc.) can be disposed of separately.

Similarly, in some embodiments, a portion of the subject system or device that comprises biohazard waste (e.g., a drug delivery cannula, a drug reservoir, etc.) can be separated from the remainder of the device and disposed of according to biohazard waste handling procedures. Separation of the biohazard waste from the remainder of the device reduces the amount of biohazard waste, as the non-biohazardous components (e.g., the electronic components) can be disposed of separately.
